k in the town that when he came back he would be married
to Miss Armstrong, and we all expected it. First thing I knew, I got a
letter from him, in the west. He seemed to be excited, and he said
Miss Armstrong had taken a sudden notion to go home and he sent me some
money. I was to watch for her, to see if she went to Sunnyside, and
wherever she was, not to lose sight of her until he got home. I traced
her to the lodge, and I guess I scared you on the drive one night, Miss
Innes."

"And Rosie!" I ejaculated.

Riggs grinned sheepishly.

"I only wanted to make sure Miss Louise was there. Rosie started to
run, and I tried to stop her and tell her some sort of a story to
account for my being there. But she wouldn't wait."

"And the broken china--in the basket?"

"Well, broken china's death to rubber tires," he said. "I hadn't any

the Carrington woman didn't show up until the night Mr. Halsey
disappeared. She came to the office late, and the doctor was out. She
waited around, walking the floor and working herself into a passion.
When the doctor didn't come back, she was in an awful way. She wanted
me to hunt him, and when he didn't appear, she called him names; said
he couldn't fool her. There was murder being done, and she would see
him swing for it.

"She struck me as being an ugly customer, and when she left, about
eleven o'clock, and went across to the Armstrong place, I was not far
behind her. She walked all around the house first, looking up at the
